For Persian, now should be work translations from Arabic for days in weather, battery and clear fixed. Can test another way to set default language - Normal select:
Translate? - Persian,
Set default language? - Arabic,
Set Mi Band to Global? - Set default language another way?
For try set in N&F default language. If no work then must be used N&F with Arabic language
And I recommend translate Updates strings to english because Persian characters aren't supported. (Connect to app to update, Updated, Updating, Updating fonts, Updating resources, Couldn't)
